High-Capacity Industrial Water & Environmental Systems
Pre-engineered skids, modularized container units, and customized high-pressure membrane concentration solutions fabricated for global turn-key deployment.
The Global Landscape of Industrial Water & Environmental Engineering
Stringent discharge limits, critical groundwater depletion, and intensifying ESG mandates necessitate scalable, energy-conscious membrane separation systems.
Across the international manufacturing landscape, industrial facilities are operating under an unprecedented convergence of ecological regulation, escalating freshwater tariffs, and corporate carbon-neutrality pledges. From chemical industrial parks along the Rhine and Gulf Coast to microelectronics corridors in Southeast Asia and oilfields across the Arabian Peninsula, access to reliable, high-purity process water has transformed from a routine utility expense into a core business continuity imperative.
The regulatory paradigms enforced by the EU Water Framework Directive, the US EPA Clean Water Act, and national mandates throughout the Middle East and East Asia have tightened the limits on total dissolved solids (TDS), heavy metals, chemical oxygen demand (COD), and persistent organic pollutants. Consequently, simple biological or conventional chemical treatments are no longer sufficient. Industrial operations are heavily migrating toward Zero Liquid Discharge (ZLD) and Minimum Liquid Discharge (MLD) frameworks, where over 95% to 99% of incoming industrial wastewater is recovered and recycled back into cooling towers, high-pressure boiler feeds, or primary production processes.
Water Scarcity & Industrial Resilience
By 2030, the global demand-supply deficit for industrial-grade freshwater is projected to exceed 40%. Leading semiconductor, automotive, and petrochemical manufacturers are deploying closed-loop membrane recycling networks to insulate operations from regional drought and utility shutoffs.
Regulatory Enforcement & Penalties
Discharge permits now penalize high-salinity brine disposal into municipal sewer systems and surface waterways. Facilities face steep volumetric surcharges and operational suspensions without integrated high-recovery concentration systems.
Decarbonization & Scope 1-3 Reductions
Modern environmental engineering demands water-energy nexus optimization. Transitioning from thermal brine evaporators to high-pressure Disc Tube Reverse Osmosis (DTRO) systems cuts energy intensity by up to 65% per cubic meter treated.

China Factory Supply Chain Resilience & Engineering Agility
Combining world-class component sourcing, automated structural fabrication, and in-house FAT testing to deliver unmatched capital efficiency.
In global industrial procurement, balance-of-plant reliability hinges on the integration quality of pressure piping, valving, high-pressure pumps, and automated instrumentation. As a premier Shanghai-based environmental equipment manufacturer established in 2010, Tongjie integrates R&D, precision skid fabrication, electrical panel assembly, and comprehensive wet testing entirely within our specialized production facility.
Our strategic manufacturing base in Shanghai's Jiading Industrial District leverages direct access to the world's dense industrial cluster for high-pressure hydraulics, precision CNC machining, and specialized metallurgy (including Duplex 2205, Super Duplex 2507, and Titanium Grade 2). This domestic ecosystem provides a 30% to 45% capital expenditure (CAPEX) advantage over North American or European skid builders, coupled with accelerated delivery schedules that shorten delivery cycles by weeks.
Tier-1 Component Tiering
We combine China's high-efficiency skid manufacturing with premium international core components: Danfoss high-pressure positive displacement pumps, DuPont FilmTec and Hydranautics membrane elements, Siemens S7-1500 PLCs, and Schneider low-voltage switchgear.
Modular Containerization Architecture
Systems are fully built into standard 20ft/40ft high-cube ISO shipping containers with anti-corrosion marine epoxy coatings, internal climate control, leak detection sumps, and plug-and-play flange connections, allowing rapid on-site commissioning within 10 to 15 days.
100% Factory Acceptance Testing (FAT)
Every system undergoes full hydraulic pressure integrity tests, sensor calibration, electrical loop checking, and wet-testing with simulated water chemistries in our testing bays prior to dispatch, eliminating on-site engineering delays.
